Three smileys. Sad, mediocre and happy next to each other.

Our goal: satisfied customers

We can only be successful in the long term if our customers are satisfied. That is why our offering is geared to the interests of our customers. And that's why customer satisfaction is one of the most important indicators in the evaluation of our business success.

Sustainably increase customer satisfaction

We use various methods to create transparency about the satisfaction of our customers with the aim of continuously improving customer satisfaction.

Customer Satisfaction Score (CSAT, 5 star rating)

Measuring and improving customer satisfaction on an operational level means living customer proximity every day. The CSAT serves ideally for this undertaking. Our customers can get in contact with the bank by many different channels such as visiting one of our branches, calling our service center or visiting our mobile app. Each channel comes with its own challenges in order to make it comprehensible and customer friendly. For this reason we constantly survey customer experience, separately for each channel. The results of the survey are then processed and support the improvement of our customer experience.

Strategic survey of customer loyalty

Commerzbank also gathers important information as part of its strategic customer loyalty survey "Kundenbarometer". For this purpose, the bank surveys around 7,000 customers in the Private and Small-Business Customers segment over the course of the year. It also surveys around 1,000 customers in the Corporate Clients segment. The survey includes key figures on overall satisfaction, recommendation and competitive advantage. These are then aggregated to form the "KUBIX" customer loyalty index. An assessment of individual elements of the bank's performance, such as product and service components, supplements the indicators. Together, this information is intended to help improve the qualitative perception of customers.

Customer-centric product and service development

Customer satisfaction also depends on whether the products and services meet and support the needs and requirements of customers using them.

The UX/UI department accompanies new and further digital developments and initiates customer-centric innovation processes. This ensures that the customer experience (CX) meets our qualitative standards. In other words, the experiences customers have with our products, services and channels are positive ones.

Customers are involved in the different phases of a product such as ideation, conception, design and development. This creates a continuous dialog, sometimes in the "User experience (UX) Studio" which is set up specifically for this purpose.
